A coalition of civil liberties groups and technology companies, including Pulver.com and Sun Microsystems, is appealing a federal court ruling that forces Internet service providers to create backdoors for government wiretapping.

The coalition on Friday asked the full U.S. Court of Appeals in Washington, D.C., to review a June 9 ruling that sided with the Bush administration.

That 2-1 ruling (PDF) said that Internet providers must rewire their networks and follow a complex scheme of eavesdropping regulations. The deadline is set for May 2007.
